AQUALINED EDI SYSTEMS
Standard CDI-Low systems are produced starting from 0.39 m3-hour capacity up to 40.88 m3-hour capacity. It consists of single or up to 8 parallel connected IONPURE® CDI-LX modules. On its chassis are power supplies, controllers, piping, sampling valves, chemical cleaning connections and instrumentation that measures the flow rate and quality of water. If desired, systems that can be sanitized with hot water (max 85 0C) can also be manufactured. Standard CDI - High systems are produced between 22.7 m3-hour and 136.3 m3-hour capacity. While it contains single and multiple Ionpure® VNX modules, it also includes power supplies, controllers, piping, sampling valves, chemical cleaning connections and instrumentation that measures water flow rate and quality on the chassis. Continuous electrodeionization is safe and reverse osmosis is the only chemical-free way to upgrade product water.
CDI - Low and High systems are systems that use a proprietary and reliable process that produces continuous and high quality water at 18 megohm-cm product water quality, without the need for deionization tanks or regeneration chemicals.
ADVANTAGES OF EDI SYSTEM
EDI units are mechanically simpler than typical renewable ion exchange systems.
EDI units can operate continuously 24/7 without needing to wait for deionization regeneration.
In EDI systems, product water quality does not change over time, whereas in renewable deionization, product water quality decreases as the resin begins to reach the saturation phase.
The most obvious benefit of EDI systems is the elimination of the regeneration process and the avoidance of the use of potentially dangerous regeneration chemicals - acids and caustics.
In EDI systems, regeneration does not have labor and chemical costs, instead it consumes a small amount of electricity. Since EDI concentrate (or recycle) stream contains 5 to 20 times higher concentrations of feed water contaminants, it is generally removed without the need for treatment or used in other processes.
By eliminating hazardous chemicals, workplace health and safety can be increased. Nowadays, with increasing regulatory influences, work areas, storage, use, neutralization and elimination of hazardous chemicals lead to additional costs such as documentation and surveillance to comply with the requirements set by law.
Since most of the impurities in water are dissolved salts, the deionization process generally produces water of high purity close to pure water, this process is fast and prevents the formation of sediment as a result of sedimentation.
